Natalie Sakin was taking out her garbage just after 9 p.m. when lightning struck her house on Sepia Road, Highway 404 and Finch Avenue East.
"The whole ground shook," she told CBC News. "I was hit with this pressure ... it was like this wall of pressure, my ears blew and the garage fell off the hinges. It was just a huge bang."
The lightning strike broke several windows in her home and blew the transformer. Three people were in the basement at the time; none were injured.
Special weather statement for Tuesday
The stormy weather is forecasted to return again later on Tuesday.
"Through the dinner hour, Toronto you'll get back into the rain," said the CBC's meteorologist Jay Scotland.
Roughly 11 millimetres fell at Toronto Pearson International Airport, Scotland said.
Environment Canada has issued a special weather statement for the Greater Toronto Area saying 20 to 50 milimetres of rain could fall Tuesday and into Wednesday.
"As a dip in the jet stream pushes in from the west, cooler air means the risk of not just rain, but a few wet snow showers as we work into your Thursday and your Friday," Scotland said.Suggest a correction
